View Full Version : need help with javascript scroller background

11-01-2012, 01:20 AM
I have some script I am trying to modify and would like to add an image to the background. It's a simple scroller and I just want to add a background image. I removed the style for the border in these lines of code:

if (ie4||DOM2)
document.write('<div id="fscroller" style="width:'+fwidth+';height:'+fheight+'"></div>');

I'm not sure if I can add it above or add a var to the code I received.

Below is the full code I received.

Thanks for any help!

<script type="text/javascript">

In future, if you post any code please put it in between
tags. It makes scanning your posts much easier. You can do this by clicking the small ‘#’ icon above the reply field.

document.write('<div id="fscroller" style="border:1px solid black;width:'+fwidth+';height:'+fheight+';background-Image:url(http://www.vicsjavascripts.org.uk/StdImages/One.gif);"></div>');

Don't use document.write - it ceased to serve any purpose when Netscape 4 died - since then beginners have been able to use innerHTML which has far fewer problems.

Also there's not much point in testing for IE4 when even IE6 is now dead.
